Pump-action chi-tech shotgun using energy as an ammo pool. Very valuable addition to arsenal, if you`re a fan of shotguns. A pity this addition is relatively late in game. Still, even when it is, it`s pretty relevant kind of addition.

Using energy gives this shotgun more staying power then ones using regular ammunition, and special bonus of replenishing half a clip every now and then further aids this. Damage output is not the highest, but both rate of fire and clip size aid this problem.

Although it`s pump-action, Purgator actually has two barrels and therefore can be modded to fire both barrels at once. In that configuration, Purgator is a very effective crowd control tool. Giving it ice modifications can improve the capability further, allowing it`s blasts to slow down whole hordes at once.
